Expert analysis
A couch measuring 51 in × 42 in × 36 in does not fit through a door, but it's about 5.5 in too large at the tightest point. The binding dimension is width: that is the axis where the couch runs out of room. We checked every orientation, and none places the couch fully inside. One caveat: applied practical clearance for handling (see tolerance buffer above).
